Keep Leptospirosis at Bay with These Simple Tips

It's that time of year again – the monsoon season is here! You know what that means: the soothing sound of raindrops on the roof, the greenery coming to life, and those cozy evenings with a steaming cup of chai. Ah! It’s magical. But through all this beauty, there's a danger lurking in the puddles and overflowing gutters: leptospirosis.

Now, I know it sounds like some villain coming straight out of a superhero movie, but fear not! Leptospirosis is a bacterial disease. While it can be serious, understanding it is crucial to stay healthy during this monsoon season. So, grab your imaginary raincoat of knowledge, because we're about to dive into the world of leptospirosis – what it is, how it spreads, and most importantly, how to keep yourself safe from this unwelcome guest.

According to the Pan American Health Organisation (PAHO), it is estimated that more than 500,000 cases of leptospirosis occur annually worldwide. This disease has the potential to become an epidemic, particularly following heavy rainfall or flooding.

Leptospirosis, a bacterial infection that humans and animals are susceptible to, has recently been in the headlines in Kerala, India. The state has experienced a spike in cases over the past week, worrying health officials and residents. Over the years, Kerala has seen a drastic rise in cases of leptospirosis. The number of confirmed cases has significantly increased, partly due to monsoons and resultant flooding which create perfect conditions for the bacteria to thrive.

Early History and Identification

Leptospirosis was first described by Adolf Weil in 1886, who identified a severe form of the disease now known as Weil's disease. This severe form includes symptoms like jaundice, renal dysfunction, and hemorrhages. The causative agent, Leptospira, was isolated and identified around 1915 independently by workers in Japan and Europe​.

Here’s an overview of the disease, its impact, spread, and preventive measures.

Leptospirosis - Impact of the Disease

Leptospirosis is a bacterial disease caused by bacteria belonging to the genus Leptospira. A zoonotic disease (spread from animals to humans) that spreads through the urine of infected animals, it is endemic in tropical and subtropical regions. 

How is it Caused or Spread? Is it Deadly?

It is transmitted to humans by contact with water or soil contaminated with the urine of infected animals. Common carriers are rodents, livestock, and pets. Humans can carry it through:

  • Contact of skin from contaminated water or soil, particularly when there are open cuts.
  • Drinking contaminated water.
  • Comes in contact with the urine of infected animals.

According to the National Library of Medicine (NIH), there is a mortality rate of 5-15% for severe cases.


The incubation period is usually 7–14 days but can range between 2-30 days.

Symptoms of Leptospirosis

The symptoms may sometimes be non-specific and similar to those of other diseases, making diagnosis difficult. Symptoms include:

  • High fever
  • Severe headache
  • Chills
  • Muscle aches
  • Vomiting
  • Jaundice (yellow skin and eyes)
  • Red eyes
  • Abdominal pain
  • Diarrhea
  • Rash

In severe cases, patients can develop liver failure, bleeding disorders, or multi-organ dysfunction.

Early Diagnosis

Early diagnosis is important for effective treatment of leptospirosis. The infection is treated with antibiotics such as doxycycline or penicillin. Hospitalization and intravenous antibiotics may be necessary for more serious cases.

Symptomatic Care

Supportive care with hydration and symptom management is crucial. Some people whose organs are failing may need life-support treatment in an intensive care unit to support affected organs.

How Can It Be Diagnosed?

Leptospirosis diagnosis may sometimes be difficult to detect as the signs are clinically unspecific. There are, however, a few options:

  • Blood Tests: Looking for antibodies or the bacteria itself.
  • Urinary bacteriology (urine tests): Determine the bacteria in urine.
  • Polymerase Chain Reaction (PCR): Finds the bacterial DNA inside blood, urine, or tissue samples.

Rapid diagnosis and early treatment are necessary for reducing the chances of significant complications and improving outcomes.

Is it More Prevalent in Dogs?

Animal Hosts

Yes, but it is more common in dogs as they can both be carriers of the disease and victims when infection takes place. Dogs can be exposed to the bacteria when drinking from, or ideally playing in, contaminated water sources or soil. A rodent-inhabited environment makes exposure more likely.

Symptoms in Dogs

Symptoms in dogs may include fever, vomiting, abdominal pain, diarrhea, lack of appetite, rapid weak pulse rate, depression, stiffness, jaundice, and severe muscle pain. Leptospirosis in dogs, if left untreated, can cause kidney damage or liver failure, leading to respiratory failure and ultimately death.

How to Prevent Leptospirosis

For Humans

  • Don't come in contact with contaminated water: Avoid swimming or wading in water you suspect could be contaminated, especially after heavy rains.
  • Protective wear: Use protective clothing and safety shoes in wet or contaminated areas.
  • Adherence to good hygiene practices: Wash hands thoroughly after handling animals or soil.

For Pets

  • Vaccination: Ensure all dogs are vaccinated against leptospirosis.
  • Avoid stagnant water: Prevent pets from drinking or swimming in standing water.
  • Rodent control: Keep homes and surrounding areas free of rodents, which are common carriers of bacteria.

Leptospirosis is a major public health problem, knowing the disease, and its symptoms, and taking precautions can help keep you safe. Public awareness and immediate medical help can combat this growing threat. Stay informed, stay safe, and take necessary measures to protect yourself and your loved ones from leptospirosis.

So, there you have it! With a little monsoon awareness and some easy-to-follow tips, you can keep leptospirosis at bay and enjoy the beauty of the rainy season. Remember, knowledge is power, and this power protects you from splashing into puddles of trouble.
